Specification ofLetters Patent. Patented Jan, $5, ll'dllwm implication filed February 525?, 1 909." Burial Mo." Mmtfillf To all whom it may canteen:

Be it known that l, VALEigTTINE ll. Hon-T son, a citizen of the United States, residing at Richmond, in the countyof Madison and L State of Kentucky, have invented certani new and useful Improvements in Flush-g Boxes; and I do hereby declare the following to be a full, clear, and enact description of the invention, such as will enable others skilled in the 'art to which it appertains i make and use the same.

This invention relates to improvements in flush boxes, and particularly to flush boxes arranged for {being filled and discharged? noiselessly. I The object in. view 1s the provision of means for admitting and discharging water from the flush boxthat is arranged continua ously beneath the water being discharged.

Another object of theinvention is the pro vision of an intake'valve in a comparatively large pipe and positioned beneath the tank,

in combination with a discharge valve :ar-

ran ed in substantially the same plane as the Astill further object of the invention is the arrangement of an intake valve that is inta e ivalve, and continuously submerged,

whereby the water flowing into the tank and from the-tank does so from comparatively large pipes which are in free communication with thetank, by which noise of the filling and discharging of the tank is eliminated.

Another object of the invention is the ar' rangement of air pipes for destroying the 1 vacuum in the bowl of the icloset seat, and iii 1 the discharge pipe leading from the tank to the bowl of the closet seat.

continuously submerged, having a float arranged to occupy a position on the surface of the-water, in eoinbmation with a discharge valve continuously submerged, and

arranged with a float which is normally submerged, and by reason of being submerged normally ithe pressure of "water in the tank will hold the valve closed untilthe l same has been mechanically unseated, whereupon the flow will resist any reseating thereof until the water in the tanl: has fallen below the float.

With these and other objects in view the invention comprises certain novel construe tions, combinations and arrangement of parts as will be hereinafter-more fully described and claimed.

lln'the accompanying drawings: Figure l 1 is. av sectional view through an embodiment 1 angles, a second large pipe ir In pipe 4 is formed a valve seat 5 which is arranged to accommodate valve Seat 5 is in free cominunication with pipe 7 into which is fitted a' l nozzle 8, oonastituting an injector which in turn is connected to a supply pipe 9. a The end of nozzle 8 is positioned any desired distance from valve 6 so that the momentum or force of the water being discharged from nozzle 8 will be largely eliminated by being compelled to till pipe if before the water can pass out past valve =6. ln this way no wear,

or comparatively little wear, will be caused to valve 6. Valve 6 is carried by a pivotally mounted rod or lever 10 which is pivotally mounted at 11 to a support 12. Support 12 is pref-era formed with a threaded reduoed 130 tion 13 which receives a nut 1% for clamping the same in position. At the end of lever ill, opposite valve 6, is pivotally connected a reciprocating rod 15 which passes upward through guiding spider 16 into tank 1'2 and is supplied with a float 17 which normally remains partially submerged, but always near the upper surface of the water so that whenever the level of the water is lowered the float will be lower ed, and consequently movement will be i t i t. J conveyed to valve b for openm the same,

and thus permitting a new supply of water to .be forced into the tank.

Secured to tank 2 at any desired place,

preferably the'end opposite to which the pipe 3 is secured, is a. pipe 18 which is of corn arativel lar e size similar to i e 3 and is formed with a seat 19 near the lower end thereof and a pro ect1on Q0. The seat ill is arranged to accommodate a valve 21 1 which has connected thereto a reciprocating shaft 522 which carries a float 23. Shaft 22 passes upward from lloat 23 and is pivotally mounted to'a lever 24 that in turn is pivotally supported at and carries its outer end a rodflfi having a thumb member on the end whereby when the same is depressed shaft 22 will be elevated and also float 23.

" 'for" shutting off the discharge.

Shaft 22 passes through a spider 27 which guides the same .in its movement. When the tank hasbeen flashed the same is not en- 1 tirely'emptied but a small amount of water 5 remains therein and is of-the same-height orflevel as the water in bowl 1. After the tank has been flushed the float 23 will be above the level of'the water and by its Weight will force valve 21- upon its seat 19 Immediately upon the water in the tank falling below its accustomed level float 17 will begin to move downward and valve-6 will be grad: ually opened so that water is continuously flowing into the tank during its discharge, but the discharge is sufficiently rapid and of suflicient volume to empty the tank even though water is flowing in at the same time.

-After the tank has been flushed valve 21 will 2 move against its seat and as the tank is filled again the weightof the water and suction at this point will resist any action of float 21 which tends to lift the valve from its seat.

However, upon manually forcing down rod 26- valve21 will be raised and float 23 will in such instance be sufficiently buoyant 'to maintain the valve raised until the float is no longer supported by the water.

Secured to the extension 20 is a discharge. pipe 28 which in turn leads to bowl 1 and is discharged at point 29 therein, though any other desired point could-be arranged for receiving the end of the pipe.

In order that novacuum or suction will be created in pipe 28 an air pipe 30 is provided which is connected with pipe 28, and

- also with tank 2 above the water line. This pipe also takes care of any overflow of tank 2. If the discharge were made into bowl 1 v 40 without anyfurther change therein after the bowl 1 had been filled to a certain extent the discharge. of water therefrom would cause a suction or-vacuum which would suck out substantially all of the water in the bowl and at the same time make considerable noise. In order to overcome this noise and the sucking action by the discharge of, the

' 7 water from thebowl an air pipe 31 is provided that is connected with the bowl at 32 'and pipe .30 at 33, whereby air is supplied to the confined space of thebowl', and consequently only the excess of water in bowl 1 will be permitted to pass therefrom. However, if it should be desirable in any instance to causea sucking action in bowl 1 for drawing out all the watentherein pipe 31 could be eliminated and the ordinary action of the water would result.
